ummm, how do you grab the nose of a wadcutter?You can use a smaller collet to grab the nose, I do it all the time. Just pulled a bunch of 8mm, .323 using a 30 cal. collet. There's no law that says you have to use a .357 collet, you use what works. Pulling just a few an inertia puller is ok. If you have very many to pull, they're slower than molasses in January.
